2 Claims.

This invention relates to new and useful improvements in wheels such asmay be used on vehicles of various kinds.

The principal object of the present invention is to provide a wheelhaving a tread construction which will absorb the shock of travelingover ruts, rocks and other uneven surfaces to a considerable degree. 3

Another important object of the invention is to provide a wheel treadconstruction which is especially adapted for tractors and farm vehicles,which must travel over uneven surfaces.

Various other important objects and advantages of the invention willbecome apparent to the reader of the following description.

In the drawings:

Figure 1 represents a side elevational viewof,

the wheel.

Figure 2 is a top'plan View.

Figure 3 is an enlarged side elevational view.

Figure 4 is a section taken substantially on line 4-4 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in the drawings that numeral 5 denotes a hub structure,while numeral 6 denotes a wheel disk, which in the present instance mayform the entire wheel, the peripheral portion being enlarged, as at i.It is possible to construct this Wheel of wood or some other inexpensivematerial, as the wear on the periphery thereof is negligible.

The tread structure embraces a multiplicity of interlaced orinter-related tread members, each being constructed of suitable wearresisting metal and being constructed in such a manner that they definesmall levers which efiect a leverage action of the wheel over unevensurfaces.

In construction each of these tread units comprises a shaft 8 disposedthrough a bushing 9 set in a transverse bore It of the enlargedportion"! of the wheel 6.

At one end of the shaft 8 is a laterally disposed arm ll, while at theother end of the shaft 8 is a second laterally disposed arm I2. Thesecond arm I2 is disposed at substantially right angles to the arm I land these arms have inwardly disposed tread bars I3, I4 which aredisposed across the peripheral portion of the wheel.

As can be seen in Figures 1 and 3, the arms I I,

I2 of "one unit interlap the arms of adjacent units.

Obviously, this wheel in operation ,will ride on wheel strikes, forinstance, a rise,the contacting tread bars recede while theircorresponding tread bars will descend, to-the end that there will be nodrop when the vehicle rides over the rise and the same action takesplace inversely when the wheel passes over, a depression.

3 While the foregoing specification sets forth the invention in specificterms, it-is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In a wheel of the character described having a peripheral portion,tread members spaced apart equidistantly around said portion and eachcomprising a shaft extending transversely through the portion andjournaled therein for rocking movement, a pair of relatively divergentarms extending from said shaft on opposite sides of said peripheralportion, respectively, outwardlyj beyond said portion and eachterminating in a right angled tread element extending-across saidperipheral portion.

2. In a wheel of the character described ha ing aperipheral portion,tread members spaced apart equidistantly around said portion and eachcomprising a shaft extending transversely through the portion andjournaled therein for rocking movement, a pair of relatively divergentarms extending from said shaft on opposite sides of said peripheralportion, respectively, outwardly beyond said portion and eachterminating in a right angled tread element extending across saidperipheral portion, the arms of each tread member being disposedcrosswise of adjacent arms of the members on each side thereof.
